IMPROVEMENT IN j STAPLE-FASTENERS.

Specification forming part of Letters Patent No. 214,166, dated April 8,1879; application filed March 4, 1879.

To all whom it may concern:

Be it known that I, GEORGE W. McGILL, of the city and county of NewYork, State of New York, have invented a new and Improved MetallicStaplc-Fastener, for fastenin papers, pamphlets, and similar articles,an for light binding of various descriptions, and in some instancesmodified as afastener adapted to suspend the same; and I do herebydeclare the following to be a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspecification, and to the figures and letters of reference markedthereon, in which similar letters of reference indicate correspondingparts.

In the ordinary wire staple, as now made, the head or body portion ofthe staple and its shanks are of the same width of metal. When papersbound by such a staple are folded or turned back over the staple-head,as is done while the papers are being read, the paper is folded andhangs back on a line with the lower edges of the punctures made in thepaper by the staple-shanks, which renders such punctures liable tofracture, and the paper to be torn oil the staple.

One object of my improved staple is to protect from such fracture thepunctures in the paper through which the staple-shanks pass, and theconsequent tearing otf of the paper at such points; and l accomplishthis end by making bot-h ends of the head or body portion of my staplewider than its shanks, so that when the papers which it binds are foldedback over it the fold of the paper will not'be on a line with endpunctures.

Another object of my invention is the construction of a wide-headedstaple, in such manner that its wide head will not interfere with thereception and sliding of its shanks in the guiding-grooves of thestaple-inserting machine patented to me by United States Letters PatentNo. 212,316, dated February 18, 1879.

In said accompanying drawings, Figures 1 u1nl3represcntmetal blanksfromwhich I form my staples, A being the head or body portion of the staple,and a, a its shanks. These shanks are bent down at slightly obliqueangles from the head on the dotted lines b b of Figsrl and 3 to theforms shown in Figs. 2 and 4, thereby forming the shoulders c c, andcompleting the staple.

Fig. 5 represents several sheets of paper bound together by my improvedstaple.

The staple may be blanked either as shown in Fig. 1 or Fig. 3, and itsshanks bent down,

,as shown in Figs. 2 and 4.

In Figs. 1 and 2 the shoulders c c extend out beyond the end of the headA, to admit the entrance of the staple-shanks into the guidinggrooves ofmy staple-inserting machine before referred to; and in Figs. 3 and 4 theshanks are cut into the ends of the head A, and are bent down tobrin'g'thcir shoulders inside of or flush with the end of thestaplehead, leaving the open spaces 0 c for the en trance'ofbevelededges of the guiding-grooves of my said staple-inserting machine.

In Fig. 5, which represents papers bound or fastened by my improvedstaple, the ends of the staple-head, being wider than its shanks,

protect from fracture the punctures or'hoies' made by them in the papersbound, and the papers, on being turned back over the staple, as beforedescribed, fold on the dotted line 9' g, and, the continuity of thepaper not being broken on said line its liability to fracture throughsuch cause is obviated.

Fig. 6 represents my improved form of staple, having its wide headextended on one side, and pierced to form a ring, h, adapting the stapleto hang or suspend upon a hook or nail the articles bound by it.

NhatI claim as myinvention, and desire to secure by Letters Patent, is-

1. A paper fastening staple having both ends of its head or body portionwider than its shanks, to protect from fracture the points of puncturemade by its shanks in the articles bound by it, and its shanks bentoutward at oblique angles from its head in a manner to form theshoulders c c, to adapt the staple to be received and operated in astaple-inserting machine, substantially as described.

2. A staple with its head wider than its shanks, and the latter bentdown so as to form shoulders c c, and having its head extended on oneside and pierced to form a suspendingring, substantially as describedand shown.

In testimony that I claim the foregoing as my own I herewith affix mysignature in the presence of two witnesses.

GEORGE W. MGGILL.
